contour farming:
Contour farming has been practiced for centuries in parts of the world where irrigation farming is important. Although in the United States the technique was first practiced at the turn of the 19th century, straight-line planting in rows parallel to field boundaries and regardless of slopes long remained the prevalent method. Efforts by the U.S. Soil Conservation Service to promote contouring in the 1930s as an essential part of erosion control eventually led to its widespread adoption.

Chemical breakdown processes in cells directly involve enzymes, which facilitate chemical reactions by lowering activation energy. Examples include cellular respiration and digestion.
All chemical breakdown processes in cells directly involve enzymes, which are specialized proteins that facilitate chemical reactions. Enzymes work by lowering the activation energy required for a reaction to occur, allowing chemical breakdown to happen more efficiently. Some common examples of chemical breakdown processes in cells include cellular respiration, where glucose is broken down to release energy, and digestion, where food molecules are broken down into smaller units for absorption.

Chemical breakdown processes in cells directly involve catabolic reactions, which form part of the cell's metabolism. Complex molecules are broken down into simpler ones, releasing energy. An understanding of this process is vital for understanding how cells, and biological systems more generally, function.
All chemical breakdown processes in cells directly involve a type of biochemical reaction known as catabolism. This is part of the cell's metabolism, which includes all chemical reactions that occur within the cell. Catabolism is the process through which complex molecules are broken down into simpler ones, with an accompanying release of energy.
For example, complex carbohydrates from food are broken down into simpler glucose units through catabolism. Furthermore, catabolic reactions also involve the breakdown of Adenosine triphosphate (ATP), the primary energy currency of cells. The energy released from catabolic processes drives different cellular activities and reactions.
The balance between catabolic and anabolic (building up) processes allows cells to harvest and efficiently use the energy necessary for their functioning. Therefore, energy is central to these cellular chemical processes. To understand any biological system, including cells and their biochemistry, it is crucial to understand how energy flows and is utilized within these systems.

B.
60
C.
30
Explanation:
the answer is c.= because meiosis is the reproduction of a germ cell with 60 chromosomes. involves splitting 60 chromosomes in half, so each cell will have 30 chromosomes in each cell..
